Decision on the number of export markets firms enter and the optimal division of labor within firms

Abstract

By constructing an intra-industry trade model with the division of labor within firms, this study shows that trade improves firm productivity through promoting the division of labor. The division of labor is limited not by the size of each market but by the number of export markets that firms enter. Free-entry condition and fixed export costs without pro-competition effect play a key role behind this result. Firms select the export markets in which they would enter depending on trade costs. As trade costs decrease, firms enter more export markets if the number of markets does not reach the upper bound. Hence, the division of labor is essentially limited by trade costs. This implication brings new insight to Adam Smith's theorem.
